A bombing of a SuperFerry by Abu Sayyaf in the Philippines' worst terrorist attack kills more than 100 passengers.

MV SuperFerry 14 was a Philippine registered roll-on/roll-off (ro-ro) ferry that was attacked on February 27, 2004 by terrorist group Abu Sayyaf that resulted in the destruction and sinking of the ferry and the deaths of 116 people in the Philippines' deadliest terrorist attack. Six children less than five years old, and nine children between six and 16 years of age were among the dead or missing, including six students on a championship team sent by schools in northern Mindanao to compete in a journalism contest.

Abu Sayyaf (ASG), officially known by the Islamic State as the Islamic State – East Asia Province, also known by its full name, Al Hamas Harakat Al Muqawamah Al Islamiyyah or simply Al Harakat Al Islamiyya, was a Jihadist militant and pirate group that followed the Wahhabi doctrine of Sunni Islam. It was based in and around Jolo and Basilan islands in the southwestern part of the Philippines, where for more than five decades, Moro groups had been engaged in an insurgency seeking to make Moro Province independent. The group was considered violent and was responsible for the Philippines' worst terrorist attack, the bombing of the MV Superferry 14 in 2004, which killed 116 people. The name of the group was derived from Arabic abu, and sayyaf. As of April 2023, the group was estimated to have about 20 members, down from 1,250 in 2000. They used mostly improvised explosive devices, mortars and automatic rifles in their attacks.
